Be it known that we, BENJAMIN J. DAVIS and ISAAC S. CRAMER, ofSergeautsville, in the county of Hunterdon, and State of New Jersey,have invented ancwfand improved Cribbing Preventer and we do herebydeclare that the following is a full, clear, and exactdesoriptionthereof, which willenable those skilledi'n the art to make and use thesame, reference being had to the accompanying drawings, forming partofthis specification, in whichj Figure 1 is a perspective view, showingthe location of the cribbing preventer on the throat-strap of abridle.

Figure 2 is a central vertical section of the lame enlarged to fourtimes its proper size.

Figure 3 is n. top view of the cribbing preventer, showing the line :1;from whence the section sho-wn at iig. 2 was taken.

Similar letters of reference indicate corresponding parts. Thisinvention relates to an attachment for bridles for the purpose ofpreventing horses from indulging in the vicious and hurtful habit ofcribbing, so called. It consists of apricking-point enclosed and guardedby all cylindrical cap working within a larger cylindrical base, towhich it is attached by a teleseopcjoint. The two V cylindrical partsenclose the pricking-point, which is firmly seated in the throat-strap,and presents its point through a central hole in the cap when the latteris pressed against the tension of a spring, which otherwise keeps thecap out and over the pricking-point.

Fig. 1 "shows the invention in place, at D, on the throat-strap of acommon bridle. The other figures more2' i fully illustrate itsconstruction. A

A. is'the strap, to which the cylindrical part B is attached, by meansof projections m m passing through the throat-strap,and keyed by a wire,z', passing through holes in the said projections, in the manner shown;The pricking-point a is Pet into the throat-strap by a flaring base, asshown, or by a washer and shoulder, or in `other suitable manner. Thispoint is located in the centre of the parts surrounding it, so that aportion .of it will be presented through the central hole k in the cap Cwhenthe latter is forced-inward.v The part B is made with a ilange, r,to meet and stop the flange n on the cap C, as shown; thus the latterworks within the part B in a manner similar tothe joints of a telescope.The helical springs is coiled around the pricking-pont,

and exerts its tension to keep the cap C thrust out, so that the point ashall not inflict pain'or prick the animal in any manner other than theone intended.

A horse addicted to the vice of cribbing generally seizes with his teethsomo'stationary wood, as the manger,

post, or fence to which he is hitched, and, bending the head, so thatthe angle formed by the head and neck is very acute, proceeds to make agurgitating noise', resembling and vconsidered to-be the swallowing ofair-a practice which has a pernicious and hurtful e'ect upon the horse,and which detracts from his value as a mer# charitable animal. -v

Now, when the invention hereinabove set forth is attached to thethroat-strap of a bridle or halter, in manner v shown at `iig. 1, theanimal cannot practise the habit above described, for when the head isdrawn in vertically, and the neck arched or flexed, the cap C .ispressed upon by theneck, and thrust down against the tension of thespring a till the prickinglpoint a is presented through the hole 7a,which, when the animal feels, he will desist from the attempt and returnhis head to its ordinary position.

Many devices for the same purpose have been patented, but they are allliable to objection. They are either `too bulky, or too severe, or thepoints are not suiiciently guarded, or are often inoperative, or are toocomplicated and expensive. Our invention presents none of theseobjections, but is at once a safe and simple cribbing preventer, smallin compass, and of a variable degree of severity, giving to the colt oryoung horse just learning 'the habit a gentle reminder to desist, or toone more fixed in thc practice a severer pricking, according as the headis bent .with more or less determination.

Weare aware that a'patent is'issued for'an invention for this purpose,in which the pricking-point is enclosed ina spherical soft-rubber guard,but this is found ineiective, as the flexible nature of the rubberpermits it to be crowded over and upon the pricking-point,thus-preventing/the proper action of the latter.

The parts B and C in' oui` invention ean be mede of metal, or may bemade of hard rubher, which` letter would, perhaps, be more desirable insome cases I We do not. claim broadly the presentation of apriekng-point guarded when not yin operation g but l What We claim asnew, and desire to secure by Letters Patent, is

The parts C and B, the one'sliding within the other, in combination withythe pricking-point a` and spring s, all substantially as shown :mddescribed, for the purpose of preventing horses from indulging Ain thesra-called habit of eribbing, al1 as set forth.
